Succession to the Crown Bill

Before my noble and learned friend sits down, is there not a terribly simple way out? That is, to say that there is no bar to any Catholic becoming King or Queen but, in the event of a new sovereign being unable to be in communion with the Church of England, a Regent would be appointed as supreme governor of the Church of England. That would help us should there be some other religion to which a sovereign might wish to belong. It would also get out of the way of this being a stitch-up between churches instead of being a proper decision by the individual concerned.
